To refresh/sync content in the Barnes & Noble NOOK App for iOS:
1. Place your finger at the top of the screen and pull downward. The screen will be pulled down with your finger.
Note: Ensure that you pull downward within the app and do not bring down your phone or tablet's Notifications menu
2. Once the screen has been pulled down, remove your finger from the screen to refresh the app. A refresh icon will appear to identify that the app is syncing.
After syncing your Library, any content that you had begun reading will open to the more recently viewed page the next time it is accessed.
